Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 22 points:

(3,4)(5,6)(7,8)(9,12)(10,14)(11,13)(17,21)(20,22);(3,4,5,6)(7,8)(9,12)(10,14)(11,13)(16,19)(20,22);(7,9,11,14)(8,12,13,10)(15,16)(17,20)(18,19)(21,22);(9,14)(10,12)(15,17,18,21)(16,20,19,22);(7,10)(8,9)(11,12)(13,14)(15,16)(17,20)(18,19)(21,22);(3,4)(5,6)(7,8)(9,10)(11,13)(12,14)(15,16)(17,20)(18,19)(21,22);(1,2)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((3,4)(5,6)(7,8)(9,12)(10,14)(11,13)(17,21)(20,22), (3,4,5,6)(7,8)(9,12)(10,14)(11,13)(16,19)(20,22), (7,9,11,14)(8,12,13,10)(15,16)(17,20)(18,19)(21,22), (9,14)(10,12)(15,17,18,21)(16,20,19,22), (7,10)(8,9)(11,12)(13,14)(15,16)(17,20)(18,19)(21,22), (3,4)(5,6)(7,8)(9,10)(11,13)(12,14)(15,16)(17,20)(18,19)(21,22), (1,2));
